There are about 4372 clinical studies being (or have been) conducted in Greece. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Irritable Bowel Syndrome (IBS) is a common functional bowel disorder characterized by absence of any organic cause. The vast majority of patients associate their symptoms with specific food consumption, creating the need for developing a new therapeutic approach based on altering the dietary habits. The aim of the study focuses in the comparison of the efficacy of two dietary patterns, the adjusted to the Mediterranean Diet Low FODMAP Diet (MED-LFD) and the nutritional guidelines of the British National Institute for Health and Care Excellence (NICE) Managing IBS.
IQOS ("I-Quit-Ordinary-Smoking,") is a type of "heat-not-burn" (HNB) tobacco product. There is evidence of a growing number of young people who try IQOS as a 'safe' alternative of cigarette. The effect of the acute exposure to IQOS smoke on pulmonary function of healthy non smokers has not been studied extensively. Objectives: Evaluation of the acute effects of IQOS on pulmonary function,exhaled CO, O2 Saturation, arterial pressure and heart rate. Methods: Healthy non smokers, underwent exhaled CO measurement, spirometry including flows, volumes and diffusion capacity, and measurement of their respiratory resistances at 5, 10 and 20 Hz (R5Hz, R10Hz and R20Hz) with the use of an impulse oscillometry system (IOS) before and after the use of an IQOS. Additionally heart rate and arterial blood pressure were also measured.
This study compares the effect of two doses of semaglutide (1.0 mg and 2.0 mg) in people with type 2 diabetes (T2D). People taking part in the study will take the medicine together with their current diabetes medicine (sulphonylurea and/or metformin). Participants will get a dose of either 1.0 mg or 2.0 mg semaglutide once a week - which dose is decided by chance. Participants will inject semaglutide under the skin once a week. The study will last for about 49 weeks. Participants will have 9 clinic visits and 2 phone calls with the study doctor. At the visits participants will have blood taken and eye tests done. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period. Female participants who can get pregnant will be checked 11 times for pregnancy via urine tests.
Non-invasive diagnosis and treatment of nonalcoholic fatty liver disease (NAFLD) remain unmet medical needs. Aim of this study is to investigate the blood levels of three hormonal systems related to obesity, insulin resistance and inflammation in patients with different stages of NAFLD, in order to identify potential diagnostic markers. Study aim: To compare the blood levels of: a) proglucagon-derived hormones (glucagon-like peptide [GLP]-1, GLP-2, glicentin, oxyntomodulin, glucagon, major proglucagon fragment [MPGF]), b) follistatins-activins (follistatin-like (FSTL)3, activin B), c) IGF axis (insulin-like growth factor (IGF)-1, total and intact IGF binding protein (IGFBP)-3 and IGFBP-4, in 18 individuals with early stage NAFLD vs. 14 controls To explore the levels of GDF-15, total and intact, in NAFLD versus obese controls (OC) at baseline and during oral glucose tolerance tests (OGTTs)
This randomized, single-center, prospective study seeks to compare the conventional radial approach with the recently described distal radial approach (anatomical snuffbox) concerning the patency of the radial artery in patients subjected to coronary angiography or percutaneous coronary intervention.
This study will assess the hereditary component of pancreatic cancer in the largest series of patients up to date through the parallel analysis of 62 cancer-associated genes. The investigators will obtain germline DNA from blood samples that have been collected from 2000 to 2019 from patients with pancreatic cancer. The investigators plan to analyze germline DNA for mutations and single nucleotide polymorphisms (SNPs) in genes that have been previously linked to a predisposition towards cancer. The outcome can provide useful insight on the overall understanding of pancreatic pathogenesis while possible associations with age of diagnosis, tumor stage and other cancer types might arise. In addition to that, it can lead to the characterization of new variants or even new genes that predispose to pancreatic cancer. Confirmed deleterious mutations in established cancer genes can provide valuable clinical information that can lead to effective, individualized patient management. Furthermore, family relatives of the individuals found to carry mutations can also benefit from established screening protocols for various cancer types, such as frequent colonoscopies in the case of an MMR mutation predisposing for Lynch syndrome, or preventative surgeries in the case of a deleterious BRCA1 or BRCA2 mutation. In addition to that, specific therapies that have been previously shown to be effective in breast or ovarian cancer patients with BRCA1 & BRCA2 mutations, such as platinum-based chemotherapy and PARP inhibitors can be also effective in mutations carriers with pancreatic cancer.
The investigators intend to study the safety and effectiveness of opioid free anesthesia compared to opioid anesthesia in ambulatory surgery in children, regarding postoperative pain, hemodynamic stability, agitation and discharge times. Quality of postanesthetic care was estimated in a 24h follow up.
Open inguinal hernia repair is one of the most common surgical procedures. Despite the fact that different of anesthetic procedures are proposed as alternatives to spinal anesthesia, the combination of spinal anesthesia with open inguinal hernia repair is preferred from both surgeons and patients. One disadvantage of this combination is the high incidence of post-surgery urinary retention, especially in men above 50 years old. This complication is partially attribute to overstimulation of the a1 adrenergic receivers of the bladder and the prostate. Preoperative administration of elective a1 blockers could inhibit this effect without side effects, since this drugs don't have systemic effect.
Bioequivalence study between two inhaler products of fixed dose combination of fluticasone propionate and salmeterol xinafoate inhalation powder
Legumes are rich source of proteins and dietary fibers which are associated with satiety and amelioration of postprandial glycemic response. The purpose of the study is to examine the effects of cereal-based products fortified with legumes on appetite regulation and body weight management.
